GAS-BURNER.

Specification of Letters Patent No. 22,609, dated January 11, 1859.

To all whom t may concern:

Be it known that I, VILLIAM WTRIGHT, late of St. Louis, State of Missouri, but now of the city, county, and State of New York, have invented a new and useful Improvement in Gas-Burners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure l is a vertical section of a burner with my improvement. Fig. 2 is a side view of the doubleeflanged perforated cup which constitutes my invention. Fig. 3 is a sect-ion of the double-flanged cup in the plane shown by the line m, m, in Fig. l.

Similar letters of reference indicate like parts in all the figures.

This invention consists of an improved article of manufacture, viz. a gas burner provided with a double-flanged cup, having openings and otherwise constructed substantially ashereinafter shown and described.

To enable others to make and use my invention, I will proceed to describe its construction and operation.

The burner A, B, which I have shown as having my invention applied, is of the fish tail kind. The application of the invention is not however limited to that kind, but is applicable to any other. The socket A is made deeper than is customary in order that it may receive the double flanged cup C, and yet leave depth enough to screw it on to the pipe by which it is to be supplied with gas. The cup C, has a funnel-shaped interior terminating at the bot-tom in a point. It is made with two fianges a, and b, the former round the top and the latter near the bottom; and upon the eXteriors of these flanges screw threads are cut to fit the .screw thread c, which is cut in the socket A, to receive the supply pipe. through it holes CZ, (Z, whose aggregate area is less than the area of the oritice at which the gas is consumed, and there are other holes e, e, drilled obliquely through the sides of the cup to form a communication from the space g, between the flanges a, b, to the interior of the cup, the Obliquity of the said holes being such as to make them converge downwardly, and thus to direct the streams The fiange b, has drilled of gas passing through them from outside the cup, down to the bottom thereof. The holes c, e, may correspond in size and num` ber with those cl, d, but are arranged midway between them, as shown in Fig. l. At the bottom of the cup C, there is a notch f, to receive a screw-driver by whose aid the cup is screwed up to the top of the socket A. At the top of this socket there is a wiregauze diaphragm It, but that constitutes no part of my invention.

The gas entering the socket of the burner is intercepted in its upward process by the fiange I), and only permitted to pass into the space g, through the holes d, CZ. The streams passing through the above-mem Ationed holes are intercepted by the flange a, and strike the conical exterior of the cup, and are thus defiected or driven back in a downward direction and distributed in the annular chamber g, whence the only outlet is through the descending holes or passages e, e, into the interior of the cup. The Streams passing through e, c, meet each other at the bottom of the cup and tend to intercept each other and hold each other back before they are allowed to slowly mingle within the cup and pass upward to the burner. The interception of the gas by the flange again by the flange CZ, and afterwards by the streams passing down through e, e, and striking each other within the conical chamber bottom of the cup C, causes a most effectual reduction of any excessive or undue pressure that it may have had on entering the lower part of the socket of the burner; and the emission of gas from the burner is thereby in a great degree equalized and its consumption is economized. This double flanged cup differs from the many contrivances used for intercepting and giving a circuitous direction to gas in burners for the purpose of reducing undue pressure more particularly in its causing separate streams of gas to intercept one another by striking one another in a downward direc` tion by being caused to issue from suitably directed oblique passages e, e, which action I find produces a very important effect.

I do not claim the reduction of excessive pressure in gas-burners by so constructing the burners as to cause the gas to be intercepted and divided into small streams and to pass in a eircuitous direction; as I am flanged cup C, having openings (d, d, e, e)

aware that therevare many gas-burners so constructed; but

I claim and desire to secure by Letters Patent, as an improved article of manufacture- A gas burner provided Wit-h a double and otherwise constructed substantially as herein shown and described.
